Throughput Analysis for Shallow Water Communication Utilizing Directional Antennas

Underwater communication relies on acoustic links due to its long propagation and low attenuation properties. Despite the advantages of using acoustic links over Radio Frequency (RF), the major drawback is the limited bandwidth of the acoustic spectrum. To circumvent this, the authors advocate the use of directional antennas rather than the traditional omni-directional antennas to boost the network throughput by taking advantage of the spatial spectrum. In this paper, they analyze the network throughput for shallow water communication with directional antennas. Unlike traditional Line-Of-Sight (LOS) directional communication, their analysis will aim to factor in Non-Line-Of-Sight (NLOS) links in the throughput analysis.
